SPECIFICATION forming part of Letters Patent No. 397,929, dated February 19, 1 889.

Application filed June 13, 1888. Serial No. 276,963- (No model.)

To aZZ whom it may concern: WVhere my invention is applied to anvils Be it known that I, VJILLIAM H. MELANEY, such as shown in Figs. 1 and 2 the body a of a resident of Pit-tsburg, in the county of Allethe anvil is formed of cast-steel, the horn c gheny and State of Pennsylvania, have inis formed of the same material, while the fac- 5 5 1 5 vented a new and useful Improvement in ing 1) on the anvil is formed of chilled cast- X Hammers or Like Dies; and I do hereby deiron, the chilled cast-iron being united to the clare the following to be a full, clear, and exbody aof the anvil by fusion, so as to form an act description thereof. intimate and perfect union therewith. The

My invention relates to anvils, hammers, body a extends under the rear end of the 60 or like dies, its object being to provide an chilled face, as at (I, so giving a support to anvil or hammer or other die which possesses the entire chilled facing, and this body a is in its body such strength as will enable the formed of homogeneous or low-grade steel, body to resist without fracture very severe which has all the strength and toughness necblows or jars, while at the same time the wearessary to sustain the jar or blows brought 65 ing face or faces are formed of such hard upon the chilled surface of the anvil, while metal as will resist the wearing action of the the chilled castiron of the facing b is so hard continued impact or blows upon its surface, that it will withstand, without appreciable so that the life of the anvil, hammer, or like i wear, the blows brought upon it in the forgarticle is greatly extended. ing and like operations generally carried on 70 In anvils my improvement also relates to 011 the surface of the anvil.

On accountof theintimate contact, in most cases the chill being placed in the bottom of the mold, though, if desired for any particular reason, it may be placed either in the sides or top thereof, and the chilling cast-iron is first run into the mold, when, as it comes in contact with the moldchill therein, that portion thereof in contact with the mold-chill becomes chilled or rapidly congealed, so forming the chilled or hardened facing thereon, and immediately after the cast- These 5,

in the horn or beak of the anvil, this part of the anvil is heated in a suitable forge and is then forged out, being drawn under a hammer to the desired shape, and a perfect surface formed thereon, while the metal is so compacted and strengthened as to make this part of the anvil,which has gei'lerallybeen con sidered the weakest part, sutiiciently strong The working-face h, formed of chilled cast-iron, may then be ground or planed, as desired, so tin- By my invention I am thus enabled to provide anvils, hammer-dies, &c., which, while having the hard surface adapted to withstaml the wear which is obtained by the chilled castiron, have also the necessary toughness and strength of body, so that there is practically no liability of breaking or crushing of the anvil or die, and the chilled facing is properly supported by the tough and strong metal forming the body of the article. In anvils I am also enabled to obtain an anvilhaving su-' perior qualities at a practically low cost, as in order to obtain the desired strength within the anvil it has been generally considered necessary to forge the anvil from wrought metal and weld a steel face thereon, this being a costly and laborious operation and in my improved anvil I obtain without the labor of forging the enti re article or weld i n g the 'faci n thereon an anvil having a tough and strong body and stiffened finished horn and a facing which is much harder and better suited to resist wear than is obtained in anvils of other manufactures, as above referred to.

'What I claim as my invention, and desire to secure by Letters Patent, is

1. As a new article of manufaeture, an anvil, hammer, or like die having a body of caststeel and afacing of chilled cast-iron united thereto, substantially as and for the purposes iron is run into the mold the steel is poured therein, and this steel entering the mold com es 1 chilled facing formed in the mold and unites in contact with the entire surface of the therewith by fusion, the molten steel, on ac 1 count of its greater specific gravity, floating or dischargii'ig from the mold any molten or unchilled cast-iron therein, so that there is a perfect contact and intimate union between the chilled shell and molten steel forming the body of the anvil or hammer-die.

In hammer-dies such as shown in Fig. 3, or stamping-dies such as shown in Fig. 1-, the dies are practically finished in the casting operation, it only being necessary in some cases to grind or plane the surface of the dies. In E the manufacture of anvils, however, in order 1 to obtain the n eccssary strength and thickness set forth.

As a new article of manufacture, an anvil having its body and horn formed of cast:- steel and a facing of chilled cast'iron on' the face of the anvil united to the body, substantially as and for the purposes set forth.

As a new article of manufacture, the anvil having its body formed of cast-steel and a facing of chilled cast-iron on the face thereof united to the body, and a horn or beak formed of forged steel, substantially as and for the purposes set forth.

' In testimony whereof I, the said \VILLIAM. H. MELANEY, have hereunto set my hand.
